Wide input range, low profile package, parallel operation for higher power
The GPD500 500W DC:DC converter now available from Gresham Power Electronics, the Salisbury based Defence and Commercial power conversion specialist, has been designed for use with fixed and mobile communications and security systems on tactical and non-tactical vehicles.
Sophisticated electronics developed for military vehicles, is designed to be powered from 24/28VDC and in most cases is unable to operate from the 12VDC electrical systems found on non-tactical vehicles. Instead of making significant changes to the equipment design, this issue is solved by the new GPD500 DC-DC converter from Gresham Power.
GPD500 low-profile DC:DC converters have a wide-range DC input voltage from 10 to 20V, feature ultra-high efficiency of typically 96% at full load and can operate over an ambient temperature range of -40° to 70°C.
The GPD500 delivers a steady, regulated 24VDC output at 500W and is designed to meet the requirements of MIL-STD 1275D enabling users to swiftly deploy equipment onto vehicles with 12VDC electrical systems.
Applications include military, non-tactical, homeland security and recreational vehicles, marine and other rugged environments, mobile broadcast, cellular base-station power, industrial controls, emergency backup power, solar and alternative power systems.
Manufactured with fully sealed epoxy resin encapsulation rated to IP67 and meeting MIL-STD-1275A standards the units provide high-reliability operation while withstanding exposure to harsh and complex environments. Dimensions are (L,H,D) 149x27x119mm and weight 750g.
The GPD500 power module has a built-in thermal sensing device providing over-temperature shut down with automatic recovery, reverse input protection, current limit protection, short circuit protection, input under-voltage shut down and overvoltage protection. It is also possible to connect several units in parallel to achieve higher power.
